HOLLOW DIBBLE.

Application filed April 25, 1922. Serial No. 556,515.

. To @ZZ whom t may concern.'

Be it known that I, Hononn HANSEN, residing at Charlottenlund, near Copenhagen, Denmark, have invented certain new and useful Improvements in Hollow Dibbles, of which the following is a specification.

lVhen holes for small plants, onions, etc., are made with a common dibble it is a great inconvenience that the sides and bottom of the hole are pressed hard, because the hole is produced simply by the dibble displacing a certain volume of earth. Furthermore the hole tapers to a point at the bottom.

It is `difficult for the root fibres to penetrate through the hard sides andbottolnV ot the hole.

In order to avoid said .inconvenience semicylindricz'xl planting' spoons are etten used, with which a hole is dug; out, but, this leads to the inconvenience that several thrusts .must be made and the loosened earth be removed betere the holo is ready.

nfcordiiugT to the invention these inconveniences are avoided, a planting' hole the sides and bottom ot which are not pressed hard being made by onethrust, whereby the bottom of the hole is broad The drawing shows a constructional form of the device.

The device consists of a conical tube a ot metal or other suitable material, open at both ends. At one end-the narrow end :in case of a conical tube-the tube is cut by a cut not perpendicular to the axis of the tube. The other end of the latter is provided wth a handle b. 1

`When a hole is dibbled the earth filling out the interior of the tube by its insertion is taken up with the tube so that by one single thrust a hole is produced whose bottom and sides are easily permeable to the root libres.

The details of the device may be altered without departing from the principle of the invention.

I claim:

d dibble for making plant holes comprising a substantially conical tube open at both ends, the smaller end of which tube is cut at an angle oblique to the axis` of the tube, and the larger end of which tube is provided with a handle formed` integrally with the tube for thrusting; the dibble into the soil and withdrawing therewith a core of earth.

In testimony whereof I atiix my signature.
